Automatic speed adjustment control system of toothed roll crusher and control method

Abstract

The invention discloses an automatic speed adjustment control system of a toothed roll crusher and a control method. An image collecting module carries out image pre-treatment on ore pictures. The planar projection area S of a single ore body and the overall planar projection area SZ of the whole stack of ore are obtained through an image processing module. A programmable logic controller (PLC) automatic control module is used for controlling the rotation speed of a motor. The geometric shape of the ore and the coverage rate of coming materials are judged through an image recognition method and then compared with preset parameters in a PLC so that the rotation speed of the motor can be automatically controlled. Therefore the toothed roll crusher can operate reasonably under different work conditions, the resource waste and use failures caused by underload and overload are effectively avoided, the repairing workloads of equipment are reduced, the economic benefits are improved, and the performance advantages of the crusher are brought into full play. The PLC is used for automatically controlling the rotation speed of the motor through programming, the original electromechanical system of the crusher is not changed, the automation degree is high, and the method is simple and reliable.

Description

technical field [0001] The invention relates to an automatic speed regulation control system and a control method, in particular to an automatic speed regulation control system and a control method of a toothed roller crusher, belonging to the field of control. Background technique [0002] Crusher is an important equipment in coal mine production. Toothed roller crusher is widely used in underground coal mines and open-pit mines. However, the toothed roller crusher often encounters uneven incoming materials during use, and large pieces of material entering the crushing cavity of the crusher appear intermittently. If the toothed roller crusher wants to ensure that large pieces of material can be crushed by the toothed rollers, it must Work at high power, so that the crusher will work in an under-loaded state in the gaps where large pieces of material appear intermittently, resulting in a waste of electric energy; secondly, when the incoming materials are continuously concent...

Problems solved by technology

However, the toothed roller crusher often encounters uneven incoming materials during use, and large pieces of material entering the crushing cavity of the crusher appear intermittently. If the toothed roller crusher wants to ensure that large pieces of material can be crushed by the toothed rollers, it must Work at high power, so that the crusher will work in an under-loaded state in the gaps where large pieces of material appear intermittently, resulting in a waste of electric energy; secondly, when the incoming materials are continuously concentrated, it may cause the crusher to be blocked and the crushing motor may be overloaded. Phenomenon, a long time will damage the crusher

Therefore, the crusher is not in the best working state whether it is under load or overload, and the working life of the crusher will be greatly affected.

[0003] In order to enable the toothed roller crusher to adjust the working state according to different working conditions and give full play to the performance advantages of the crusher, there are some automatic control systems in the prior art, but the adjustment methods of these systems are more complicated, the maintenance cost is higher, and the control is reliable. Sex is not high
